J1 Terminals 1 & 5 - Residential Radio (single button) Input
These terminals are intended for use with a radio receiver in a
residential application or as a single button control. This allows
the user to open the gate by activating the remote control when
the gate is closed or between limits. This input also gives the user
the ability to close the gate by activating the remote control when
the gate is on the open limit.
J1 Terminals 2 & 5 - Shadow Loop Input
These terminals are intended for use with a loop detector and is
primarily used on swing gate operators. This input protects cars
by preventing the gate from moving off of the open or close limit
when the shadow loop input is active.

These terminals are intended for use as a general open control.
Accessories that may be wired to this input include: Telephone
Entry Systems, Radio Receiver (Commercial Applications), Exit
Loop Detector, Keypads, 7-Day Timer.

gate stopped and entrapment alarm on).
Field Wiring Terminals 8 & 5 - Interrupt (Safety) Loop Input
These terminals are intended for use with a loop detector. This
input functions to reverse a closing gate to the open limit.
Latching this input will reset the timer to close.
